Benzene is colorless liquid with a
characteristic odor and burning taste that is one of the most commonly
used solvents in the United States. Benzene is used as an additive in
gasoline and an ingredient in paints, inks, adhesives, rubbers, glues, old
spot removers, and furniture wax. Benzene is also used to make some types
of plastics, glues, rubbers, lubricants, dyes, detergents, drugs, and
pesticides. It is also natural component of cigarette smoke. Benzene ranks
in the top 20 chemicals for production volume in the United States.
However, Benzene is a known human carcinogen. Long-term exposure to high
levels of benzene in the air can cause leukemia, cancer of the
blood-forming organs. There are several ways to be exposed to unhealthy
levels of Benzene. Workers in industries that make or use benzene may be
exposed to the highest levels of Benzene and are at the highest level of
risk.
You can also be exposed to dangerous levels of the solvent from indoor air
that contains benzene from products that contain it such as glues, paints,
furniture wax, and detergents. Air around hazardous waste sites or gas
stations will contain higher levels of benzene. Leakage from underground
storage tanks or from hazardous waste sites containing benzene can result
in benzene contamination of well water. Another major source of benzene
exposure is cigarette smoke.
Industrial processes are the main source of benzene in the environment.
Benzene can pass into the air from water and soil. It reacts with other
chemicals in the air and breaks down within a few days. Benzene in the air
can attach to rain or snow and be carried back down to the ground. It
breaks down more slowly in water and soil, and can pass through the soil
into underground water.
If you believe that you have been exposed to benzene you should report
your suspicions to your employer and be tested. Several tests can measure
your exposure to Benzene. There is test for measuring benzene in the
breath which must be done shortly after exposure. Benzene can also be
measured in the blood. However, benzene disappears rapidly from the blood
and test results are only accurate if the test is performed after recent
exposure. |
